acl_copy_int - copy an ACL from external to internal representation
Linux Access Control Lists library (libacl, -lacl).
.In sys/acl.h acl_t
acl_copy_int const void *buf_p
acl_copy_intfunction copies an exportable, contiguous, persistent form of an ACL, pointed to by buf_p, to the internal representation.
This function may cause memory to be allocated. The caller should free any releasable memory, when the new ACL is no longer required, by calling acl_free(3) with the (void*)acl_t returned by
acl_copy_intas an argument.
Upon success, the
acl_copy_intfunction returns a pointer that references the ACL in working storage. On error, a value of (acl_t)NULL is returned, and errno is set appropriately.
If any of the following conditions occur, the
acl_copy_intfunction returns a value of (acl_t)NULL and sets errno to the corresponding value:
|The buffer pointed to by the argument buf_p does not contain a valid external form ACL.|
|The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.|
